OFDM PAPR Reduction by Convex Optimization: A power amplifier point-of-view
2010 (English)In: 2010 IEEE International Microwave Workshop Series on "RF Front-ends for Software Defined and Cognitive Radio Solutions", IMWS 2010 - Proceedings, IEEE , 2010, 81-84 p.Conference paper (Refereed)
In this paper we evaluate the application of convex optimization for PAPR reduction on OFDM 802.11a signal type. A radio frequency power amplifier is measured and characterized while excited by both original and optimized OFDM signals. A state-of-art test setup was used for the purpose. Figure of merits such as power added efficiency, in-band errors, and out-of-band spectral emissions are investigated for their relevance and a study of the power distribution in the excitation signal is evaluated.
